For the life of me, I can't figure this one out. I've searched high and low but haven't found an answer.
How, on an Android (2.1) phone, can I detect what band am I currently using.
No, it doesn't support locking onto single band (choices are only 2G, 2G/3G, 3G).
No, I can't ask my provider, because they support BOTH bands simultaneously.
No, I can't figure it from a coverage map, since BOTH bands cover my location.
I'm using Samsung Galaxy S (and HTC Desire when it comes from service...), both European versions that support 900MHz and 2100MHz bands (for UMTS).
Is there a way/app/script/ANYTHING that can show me what band the phone is currently using?
The reason for this is that, as I said, in my location there are BOTH types of antennas and even though the coverage is marketed as good, I get very poor signals. I suspect that the phones locks onto just one of the bands (for any reason) and that the other one might be a better choice.
3G band reception is usually worse than 2G because it has a shorter range than 2G and it doesn't have so much building/wall penetration than 2G. I suggest you try setting your phone to use 2G only (in network settings) and try it out. The phones are made so they use the fastest network even if the signal strength is worse.

Yeess...? And your point concerning my question was exactly what? How does that help me to detect which UMTS band my phone is operating on? By turning it OFF?
I'm sorry, but either you didn't read it at all, just completely missed my point, or are trying to piss me off. (sorry, I'm just sooooo tired that people don't read the posts they answer to, or just completely miss the point of the post.)
Sorry. But. UMTS = 3G. So turning 3G OFF does NOT, in the slightest, help me detect what I originally asked for.
Just to be PERFECTLY clear: YES, 3G/UMTS works on BOTH 900MHz AND 2100MHz channels here in Finland. Yes, 900MHz 3G. Not a typo.
I also want to know this question
Same here... No app... come onnnnnnn
Just type *#0011# in the dialer dude. It will tell you which band you're on.
Has anyone tried using one of the white unlocked Lumia 920 from Clove (I guess the ones from Expansys are the same) on an LTE network?
Specifically, do you have the "4G" option in the "highest connection speed" settings?
In my case, although I am using an LTE SIM with an LTE network on a supported band, I only have "2G" and "3G" options in the Highest Connection Speed settings. So normally it is only connecting over HSPA. Through playing around a lot with scanning LTE bands with the Field Test tool (##3282#), I can sometimes get the device to connect to LTE, after which it works perfectly on LTE until reboot. But it's not really a long-term solution.
The default firmware on my device is country variant "CV GB SW Variant ID 276 v03" which (apart from the version number) seems to be the same firmware as that sold by Orange / T-Mobile in the UK (i.e. for 3G networks).
I was thinking about trying to flash the EE firmware, but concerned this could create other issues (such as end up locking the phone to EE, or to certain LTE bands, or something...). Any thoughts appreciated.
You don't mention where you are, but that might help respondents.
As you may know, the LTE bands are different between the NA and Europe. The LTE Bands listed on the international version are 800/900/1800/2100/2600 while the NA(Rogers & AT&T) version has 700/850/1700/1900/2100.
Are you sure you are connecting to the LTE bands? Do you have an LTE SIM installed?

Have a look at this offivial Blog post from Nokia.
http://goo.gl/L2eiy
They basically saying that even-thought the new Lumias are LTE ready they will required a software update to turn LTE ON.
The information on that is very limited as Nokia didn't specify ANY details on how they will push this OTA.
What happens if you have an unlock device and use it in a different country of its origins? How they will push the update under what criteria?
Is the update is driven by the SIM ID? They will update the OS and turn ON LTE depending the SIM region or the device IMEI region?? Nobody knows...
Even worst there is a rumor that the latest Snapdragon S4 is supporting all 9 LTE bands at ONCE and the software just enable the appropriate ones, its programmable from the firmware. If this is true, then Nokia is committing a suicide here, they can simply program WP8 to recognize the SIM ID and turn ON/OFF LTE Bands depending the Network. Going with OTAs across different devices and regions will be a mess.

There are international versions that HAVE ALL 9 LTE bands enabled and also petaband 3G.
For example in Germany:
http://www.nokia.com/de-de/produkte/smartphones-und-handys/lumia920/technische-daten/ (expand where it says "Basisdaten")
or in Singapore:
http://www.nokia.com/sg-en/products/phone/lumia920/specifications/ (expand where it says "Hardware")
or also in Switzerland:
http://www.nokia.com/ch-de/produkte/smartphones-und-handys/lumia920/technische-daten/ (expand where it says "Basisdaten")
I think there might be a good chance that you can unlock those extra bands on international versions (RM-821) that have them disabled by flashing a different firmware version. However this is just me thinking out loud so please don't blame me if it doesn't work or if it breaks your phone!
However I would strong discourage you from flashing an RM-821 firmware to an RM-820 (North American version) as I know that sb around here almost broke his phone by doing so.
Hi all
Thanks for your replies so far.
Right now I am using the phone in Japan, where there are three carriers with Band 1 (2100 MHz) LTE networks. I only tried one carrier so far, and yes it is an LTE SIM. As mentioned, I can actually connect to LTE and have used it for several hours, it's just necessary to use an unreliable trick (with ##3282#) to get the phone to see the LTE network. This seems related to the fact there is no 4G option in my highest connection settings.
Thanks for the heads-up on the OTA updates, agreed it's not clear how this will work at all...
Regarding the LTE band support, personally (although it's just my intuition) I think the lists of 9 LTE supported bands on those regional Nokia websites are probably in error (it wouldn't be the first time). Normally the most reliable source in Nokia's website is Nokia Developers, which clearly shows five bands for global RM-821 (1, 3, 7, 8, 20) and four bands for AT&T RM-820 (2, 4, 5, 17).
While the Snapdragon baseband may be able to support all 9 bands, the most difficult part of the design is the RF - filters, amplifiers, etc. So I imagine different RF chains are used in the two variants to support these specific bands.
Again, if anyone has the unlocked RM-821 and tried with an LTE SIM, if you could confirm if the 4G setting is available in highest connection settings, it would be much appreciated.

I thought the same thing on PentaBand 3G and 9 Bands LTE, however in another discussion we verified (at least for the German model) that even thought the Nokia German website states PentaBand 3G and 9 Bands LTE, in the retail Box it only mentions QuadBand 3G (AWS missing) and PentaBand LTE.
With the Canadian model being PentaBand and Snapdragon's S4 Specs claiming that is fully supporting it, along with the programmable LTE, we really have no clue of whats really going on until Nokia, or anyone else clarify it...
I have a very bad feeling that the all 920s are PentaBand 3G and support all bands of LTE with programmable software but Nokia for some reason is locking specific bands on specific models/regions.
Hopefully in time we will clarify everything and hopefully its sooner rather than later..

Different frequency bands require different antenna design. It is probably very difficult to design an antenna that can satisfy all LTE bands even though the chipset can support it. So, instead, Nokia is probably going to selectively make different hardware with different antenna design to fit a specific region. Apple iPhone 5 uses the similar Qualcomm chipset and it only supports very limited LTE bands for international version.

For 3G PentaBand is now standard in almost all chips and since the Canadian variant comes with PentaBand on board and the fact that is standard on the S4 I really see no reason of why Nokia will order a custom version of the S4 to just physically take off the AWS. It doesn't make any sense, so if its missing, most likely is turn off in firmware.
For the LTE. Qualcomm introduced a revolutionary technology called Software Defined Radio or simply SDR and the Snapdragon S4 Plus MSM8960 chip which is inside the Lumia 920, supports that technology. With SDR the chipset support all LTE bands from a low to high frequency, it can work in everything between, of course not at the same time, the software programs what frequency the antenna should be set.
If the Lumia 920 and its S4 really have SDR technology, they it will make sense for Nokia to have the firmware deride what LTE to make available to the user, by reading the SIM region and not providing individual updated per region, or based on device product number.
This finally solves a major issue for the manufactures because they do not have to build customs chips for specific countries, the software simply programs it. If you Google it you can find a lot of info regarding SDR. Of course we are not in the engineering team of the Lumia 920 line and its obvious whatever we say here is based on theory and specs that are available to us.

If you understand radio technology at all, you should know the most important part that make all things work is the radio antenna, not the chipset. The chipset itself can't receive or transmit radio signal without a proper antenna. Try to disconnect your car radio antenna and see how many stations you can receive

We're going a bit off-topic from the thread here, but you're right - SDR defines the baseband, not the RF components.
If you look at Nokia's FCC filing for the RM-821, you can see it has two cellular antennas ("main" and "MIMO") for each of two bands ("HB" high-band and "LB" low-band). Presumably LB is used for bands below 1 GHz or so, while HB is used for bands above. So you can see it's not necessary to have different antennas for every band - bands 1 to 4 (including AWS) could also use the same antennas, for example.
However, each band needs its own RF filters to prevent interference from neighbouring channels, and also needs amplifiers that have flat gain over those bands. These RF components are usually band specific, relatively bulky and expensive, and there are some challenges to use several RF chains in parallel. To my understanding these are the limiting factors that explain why a given device tends to support maximum 4 or 5 LTE channels.

Is that a joke?? I am spending my time explaining what SDR is and I am getting that respond??
I am assuming that I am talking with a person that knows at least a modern chipset like the S4 package contains all the antennas for GSM/WCDMA/LTE a separate antenna for Bluetooth and Wifi, GPS (S4 also includes GLONASS), the CPU and the Adreno GPU.
All the above come in the same tinny chip that in the size of your nail. And all this is called the "chipset". Qualcomm does not use a separate antenna anymore its integrated to the chipset.

With respect, that's not right - the antennas and RF components are external to the chipset.
Go and get the SAR compliance test report for Nokia 920 from the FCC's website, and you can see diagrams showing the external antennas for cellular, WLAN/BT and GPS which are positioned in various places inside the phone's chassis (btw, the LB MIMO antenna is about 7 cm long!)
Or go and check out the iFixit teardown for iPhone 5 and you can see the same kind of thing...

That is correct. Many manufactures are placing antenna extensions and putting additional GPS censor in more practical areas.
The actual GSM/WCDMA/LTE modem WiFi, Bluetooth and GPS for Qualacom solutions are placed inside the chipset.

Likely they are LTE bands (e.g. band 5 = 850 MHz), but as you probably noticed they don't completely match with the LTE band support of the device. Keep in mind this field test program was probably thrown together by Nokia's R&D guys for internal testing only (not for consumers), so could be a legacy of earlier testing, another device variant, or some other reason...
Anyway, it seems fine to keep this setting on Automatic.

Hi Doug, could you share what version of the Lumia 920 you have, and which firmware?
As mentioned in my mail above, there seems no problem to leave the 4G band on automatic, and the bands available to be selected don't seem relevant. (My device picks up Band 1 LTE networks even though band 1 is not in the list).
Regarding 4G vs LTE, my device (unlocked UK CV) shows 4G in the top left when it is connected to LTE. I assume this can be changed by Nokia depending on the operator's requirement (esp in the US where 4G means HSPA...). You can be sure you're on LTE by going back to the field test menu, selecting GSM option, then looking at "Radio Access Technology". If you're on LTE, it should say LTE there.

is the LTE radio in the DNA restricted to just the 750 MHz frequency? Because the DNA antenna can hear 1900mhz and 2100 MHz, which is the AWS frequencies.
verizon stated the S4 is the first device to support the new spectrum so no previous phone will get it and even the S4 will need a software update first
I hope the frequency change will improve the signal's ability to penetrate into buildings where I work. My service is magnificent, except for at work. There, it is positively dreadful.
Sadly, looks like it's a moot point anyway, til I upgrade to my next device.

Right now Verizon runs on 750 mhz which which is very good at penetrating buildings. The new freq they are moving to is 1.9 ghz and 2.1 ghz which will not penetrate objects as well or travel as far through open space. The higher the frequency the bigger impact objects, trees, and distance have on your connection. But higher frequency also allows for more throughput so look for better LTE speeds

Personally I think Verizon is crazy to be giving up 750 MHz spectrum to go with 1.9 ghz and 2.1 ghz spectrum. I think they're doing it because you can place more towers in closer proximity using higher frequencies than you can using 750 MHz. The signal traveling further in 750 MHz also causes you to interfere with yourself, so by going to higher frequencies they can place more towers, which enables them to distribute the bandwidth across multiple towers.
So look for higher speed capabilities, and also more consistent speeds. It should improve the reliability if they are in fact going to put up more towers. Just don't expect to get much better performance than ATT or TMobile inside, since these are similar frequencies to what they run on.

They're not "giving up" anything. The AWS bands will be an overlay in congested areas.
They're giving up frequencies in the 700 MHz band that they acquired in 2008 in an auction. I'm not saying they are doing away with 700 MHz altogether, but they are giving up channels in the 700 MHz band. Hopefully the hand off between their "AWS" and LTE network (aws just being the license name of the frequencies) will be more seamless than the hand off from 3g to LTE. Otherwise we will have 3g, LTE, and "AWS" that our phones will search for and need to jump between. Every time you enter a building you'll drop AWS, try to get LTE, may or may not get LTE, then drop to 3g...
Anyone that used Sprint WiMAX can tell you how bad higher frequencies penetrate buildings.

GOD I hope they don't drop the 700 series down the road. I went with them strictly for the building penetration (I work in a hospital). T-mobile would give me zero signal indoors.
I can't see them giving it up completely until at least 2 years after they stop making phones those radios.

They're giving up lower A and B block licenses that they never did anything with anyway, due to the antenna design issues. Their existing 700mhz footprint will be entirely unaffected.
I have to assume that cross-band LTE handoff is much more robust than failover to 3g. It has to be, if they're expecting to use this network as the basis of VoLTE.
Its all in how its handed off. If you think about it as going between 2.4 ghz and 5.8 ghz on a router using the same technology just different frequency the handoff isn't smooth at all. Time will tell.

Our antenna is tuned for the right frequency, but whether or not our radio can demodulate LTE at those frequencies is a whole different story. I don't know enough about cellular wireless technology to tell you for sure.
Also, I believe other carriers are already running close to 2ghz LTE networks, so I would expect to see speeds similar to theirs. I think ATT, TMobile, and Sprint are all licensed for LTE at around 1.7 ghz - 2.1 ghz
Personally I wouldn't buy the first phone capable of running between the two different bands until it's proven itself. And I hope our phone isn't capable of running in the new bands.
Anyone know if our phone is capable of doing this? Verizon just rolled it out in Seattle (where I'm at) and my friend on his Note 3 had to go into his "Service Mode" and enable it manually but is getting 78megs down and 26 megs up (first test in a congested area). Here's a link to the article he had to read in order to enable it: http://forums.androidcentral.com/ve...enable-band-4-aws-sm-n900v-requires-root.html
After doing some searching it looks like we're SOL. Can anyone confirm? It's been a while since the last post in this thread so I am assuming things may have changed since this last post.

The s2 has a Broadcom BCM4330 wifi chip.
This chip supports till 72Mbps connection, while I get 65Mbps max on my router.
The router is configured on 802.11B/G/N (speed: MCS7).
11N is 20/40Hz.
As I see on wikipedia here, that the speeds at 20Hz 65Mbps on 800ns GI and 72,20Mbps on 400ns GI
I am still getting max 65Mbps on my phone if it's connected to my extender which can get up to MCS15.
Is there a way to maximize connection speed?

in the WIKI link of ur post i see the below
Deployment strategies
To achieve maximum output, a pure 802.11n 5 GHz network is recommended. The 5 GHz band has substantial capacity due to many non-overlapping radio channels and less radio interference as compared to the 2.4 GHz band. An 802.11n-only network may be impractical for many users because they need to support legacy equipment that still is 802.11b/g only. Consequently, it may be more practical in the short term to operate a mixed 802.11b/g/n network until 802.11n hardware becomes more prevalent. In a mixed-mode system, an optimal solution would be to use a dual-radio access point and place the 802.11b/g traffic on the 2.4 GHz radio and the 802.11n traffic on the 5 GHz radio.This setup assumes that all the 802.11n clients are 5 GHz capable, which isn't a requirement of the standard. Quite a few wifi-capable devices only support the 2.4 GHz, such as iPhone 4S, and there is no practical way to upgrade them to support 5 GHz. A technique called "band steering" is used by some enterprise-grade APs to send 802.11n clients to the 5 GHz band, leaving the 2.4 GHz band for legacy clients. Band steering works by responding only to 5 GHz association requests and not the 2.4 GHz requests from dual-band clients.

my router/modem is 2.4GHz only (i think), I have the huawei hg655d.
so no possibilities?
ps on my pc I get 300Mbps connection (atheros ar5b93 wif card)
